"I tried matcha once. It was bitter, grassy and honestly... I didn't get the hype."

If that sounds familiar, you're not alone.

For many people, their very first cup of matcha isn't a great one. Unfortunately, that single experience often shapes their opinion forever.

The truth is, not all matcha tastes the same.

In fact, two matchas can look similar on a shelf but taste completely different in your cup.

That's because the quality of matcha is influenced long before it reaches your kitchen. It starts in the tea fields of Japan, continues through harvesting and processing, and finally depends on how it's milled into the fine green powder we know and love. 

So, how do you tell if you're buying good matcha?

Let's break it down.

Beyond "Ceremonial Grade"

One of the first labels you'll come across is "Ceremonial Grade."

While it's generally used to describe matcha that's intended to be enjoyed on its own, the term alone doesn't guarantee quality. It's mostly a marketing term which was coined by one of the western countries. It doesn't exist is the Japanese Tea culture. Unlike many food certifications, "ceremonial grade" isn't a globally regulated standard, and different brands may use it differently.

Instead of relying on the label alone, look deeper into how the matcha was grown and produced.

The story behind the powder often tells you far more than the words on the packaging.

1. Cultivars: The Foundation of Flavour

Just as different grape varieties create different wines, different tea cultivars produce different styles of matcha.

A cultivar refers to the specific variety of tea plant that has been cultivated for its unique characteristics.

Some cultivars are naturally sweeter.

Some offer a richer umami.

Others have floral aromas, nutty notes or a gentle bitterness.

Popular Japanese cultivars include Okumidori, Samidori, Saemidori, Yabukita, Gokou, and Uji Hikari, each bringing something unique to the final cup. There are more than 100+ cultivars.

Some producers proudly offer single-origin, single-cultivar matcha, allowing you to experience the distinct personality of one variety.

Others create carefully balanced blends of multiple cultivars to achieve consistency, smoothness and complexity throughout the year.

Neither approach is inherently better.

Single cultivars highlight individuality.

Blends are crafted to create harmony.

The best choice simply depends on the flavour profile you're looking for.

2. The Harvest Matters

Not every tea leaf harvested during the year produces the same quality of matcha.

The highest-quality matcha is generally made using the first flush, also known as the first harvest of spring.

These young leaves have spent the winter storing nutrients, resulting in a naturally sweeter, softer and more complex flavour.

Later harvests tend to be more robust and are often used for culinary applications such as baking or cooking.

If a brand mentions that its matcha comes from the first harvest, it's usually a strong indicator that quality has been prioritised.

3. Shade-Grown Leaves: The Secret Behind Umami

One of the defining characteristics of authentic matcha is that the tea plants are shaded before harvest.

Around 20–30 days before picking, farmers cover the tea plants to reduce direct sunlight.

• This encourages the plant to produce more chlorophyll and preserve higher levels of L-theanine, an amino acid responsible for matcha's naturally sweet, savoury and umami-rich character.

The result?

• A brighter green colour
• A smoother flavour
• Less bitterness
• More depth

If a matcha brand tells you how long the tea leaves were shade-grown, it's often a sign of transparency and craftsmanship.

4. Stone-Milled Matcha: Slow is Better

Once the leaves have been harvested, steamed, dried and prepared, they need to be transformed into an incredibly fine powder.

The traditional method uses large granite stones that rotate slowly to grind the tea.

This gentle process produces an exceptionally fine texture while minimising heat, helping preserve the delicate flavour, colour and aroma of the leaves.

The trade-off?

It's slow. Very slow.

A traditional stone mill produces only a small quantity of matcha each hour.

To meet large-scale demand, some manufacturers use faster mechanical grinding methods. While these methods increase production, they can generate more heat and may compromise the powder's texture and some of its delicate flavour characteristics.

If you're looking for a refined drinking experience, stone-milled matcha is generally worth seeking out.

How to Tell if Your Matcha is Good

Even before taking your first sip, your senses can reveal a lot.

Colour

High-quality matcha has a vibrant, rich green colour that reflects careful cultivation and shading.

Poor-quality matcha often appears dull, yellowish or olive-green, suggesting older leaves or lower-grade material.

Texture

Good matcha feels incredibly fine almost like silk between your fingers.

Lower-quality powders can feel slightly coarse or grainy.

That difference becomes noticeable once you start whisking.

Aroma

Fresh, high-quality matcha has a clean, vegetal aroma with subtle sweetness.

It should smell fresh rather than stale, dusty or overly grassy.

Whisking

Even premium matcha may form tiny clumps after opening because the powder is so fine and naturally attracts moisture from the air.

That's completely normal which is why sifting is always recommended.

Once sifted, good-quality matcha should whisk into a smooth, creamy liquid with a delicate layer of fine foam.

If the powder struggles to dissolve, remains gritty or forms persistent lumps despite proper sifting and whisking, it may indicate lower quality.

Taste

Perhaps the biggest misconception is that matcha is supposed to be bitter.

Good matcha isn't.

A high-quality matcha should offer:

✔ Natural sweetness

✔ Pleasant umami

✔ Gentle vegetal notes

✔ Minimal bitterness

✔ A clean finish

Lower-quality matcha often tastes harsh, overly grassy or excessively astringent, especially when prepared without milk. The experience is not so pleasant even with milk as matcha is an acquired taste.

Mouthfeel

Great matcha has a smooth, almost velvety texture. It feels light yet creamy as you drink it.

Poor-quality matcha can feel chalky, rough or leave an unpleasant dryness on the palate.

Don't Judge Matcha by One Cup

If your first experience with matcha wasn't enjoyable, don't give up just yet.

Many people unknowingly begin with lower-quality matcha and assume that's simply how it tastes.

In reality, the right matcha can be surprisingly smooth, naturally sweet and incredibly balanced.

Yes, matcha is an acquired taste.

Its earthy character is different from coffee, chai or black tea.

But starting with high-quality matcha makes that journey far more enjoyable.

Even if you eventually decide it's not for you, you'll know you've experienced matcha as it was intended to be enjoyed and not masked by bitterness or poor processing.

Because everyone deserves to make a fair judgement based on a genuinely good cup.

Coming Up Next

Now that you know how to choose the right matcha, another question naturally follows:

How much matcha should you actually drink?

Is one cup enough?

Can you enjoy it every day?

How much caffeine does it contain, and when is the best time to have it?

In our next article, we'll answer all of these questions and help you build a matcha routine that's both enjoyable and balanced whether you're a curious beginner or someone looking to make matcha part of your everyday ritual.
